Accumulation of methylmercury in the earthworm, Eisenia foetida, and its effect on regeneration.
The environmental contaminants mercury and methylmercury cause teratogenic, nervous, and renal damage in mammals (Venugopal and Luckey 1978).

متن کاملEffect of environmental factors on cellulase production by Lyscinibacillus sphaericus from the gut of Earthworm, Eisenia foetida
Earthworms are eco-friendly and play a variety of roles in agro ecosystem. The gut of earthworm is the factory to manufacture the beneficial microbial densities and their products. The excreted nutrients enrich thousand times more than the surrounding soil. Experiments have proven that crops grown in earthworm inhabitant soils had increased the yields from 25% to over 300% than in earthworm fre...
متن کاملEffect of Eucalypus Citriodora Leaves on the Multiplication of Exotic Earthworm Species Eisenia Foetida
When different ratios of Eucalyptus leaves and cow dung were mixed and analyzed for worm multiplication, amongst the three ratios (1:1, 3:1 and 3:2), 3:1 was the most suitable ratio as far as multiplication of worms is concerned. There was no multiplication of worms up to two weeks but the worms started multiplying at a significant rate after two weeks. After eight weeks of inoculation the numb...
متن کاملComparative acute toxicity of twenty-four insecticides to earthworm, Eisenia fetida.
In this study, we used two different types of bioassay, a contact filter paper toxicity bioassay and a soil toxicity bioassay, to compare the acute toxicity of twenty-four insecticides belonging to six chemical categories on earthworm species, Eisenia fetida. Results of the contact filter paper toxicity bioassay indicated that neonicotinoids were super toxic to E. fetida (48 h-LC(50) value rang...
